adaptable to devices for drilling and performing other operations in limited spaces. 7

In the drawing Figure 1 shows an example of the mechanism in sectional elevation with the shafts operating at an angle of 45 degrees. Figure 2 is similar example with the shafts at right angles.

. 20 In both drawings i is the anving'snatt and integral therewith or secured thereto is the driving gear 2. l is a mating gear integral with or secured to the driven shaft 4. In Figure 2 the driven shaft 4 is shown with a chuck I for holding a drill or other tool. '(Jombinationjournal and end thrust bearing members and I are provided for the shafts I and l l and also for receiving the outward end thrust of the gears 2 and 3. Encasing the gears 2 and 8. shafts I and 4 and the Journal bearing members I and 1 is the housing l,'suitably bored to position the journal hearings in proper alignment. Pins 0 and II are provided tosecure the ioin'nal bearings in place.

Within the bend of the housing I and between the gears! and I is positioned a ball il' fitting concave surfaces formed in the small ends of the gears and also fitting another concave sur- 40 face one lug l2 projecting inwardly in the howincl.

When mechanism of this type is used for drilling and certain other devices, the end thrust on the driven shaft is often very heavy and the 5 cause of rapid wear, but I have found a single ball, preferably of hardened steel, mounted as shown provides a compact and inexpensive arrangement and practically eliminates this wear.

What I claim as new is:

1. In angular driving mechanism, a driving shaft, a driven shaft, means forsupporting said shafts in operative position, meshing bevel gears mounted on the shafts and a single ball in contact with the supporting means and said gears.

2. In angular driving mechanism, a driving shaft, a driven shaft, means for supporting said shafts in operative position, meshing bevel gears mounted on the shafts and a single ball in contact with the supporting means and the small ends of said gears.

3. In angular driving mechanism, a driving shaft,'a driven shaft means for supporting said shafts in operative position, meshing bevel gears mounted on the shafts and provided with ball seats, a cooperative ball seat provided by the supporting means and a single ball mountedin said ball seats.

4. In angular driving mechanism, a driving shaft, a driven shaft, means for supporting said shafts in operative position, meshing bevel gears mounted on the shafts and provided with concave pockets, a cooperative concave pocket on the supporting means and a single ball within the said pockets.

5. In angular driving mechanism, a driving shaft, a driven shaft, means for supporting said shafts in operative position, meshing bevel gears mounted on the shafts and provided with concave pockets on their. small ends, a cooperative so concave pocket on the supporting means and asingieballwlthinthessidpockets.
